what I claim as new, is

1. In a feeding mechanism of the type described, the combination of a Work holding hopper and its vertically moving selector slide, of aninclined runway, comprising a iixed'lon'gi'tudinal section formed with an inclined" upper face and a longitudinal sec tion mounted on the inclined face of the fixed.

section: and having lateral adjustment on the" inclined'face of said'section.
